does that seem low I drove probably 242 miles without going over 2000 rpm and prob 4 giving her hell I took my buddy for a ride who just put a supercharger on an 04 f150 but I just dont think 11.1 mpgs is right?

Thanks guys

Are you hand calculating and do you have larger than stock tires?

Hand calculated with my corrected speed sensor on 38" tires and mods out the nose I get nearly 16mpg all driving conditions with Erics safe street.

I'm awaiting to see what I'll be getting with a looney wild for my powermax.

You are pretty much in the same ball park as me. I get an average of just over 12 mpg. Hope it picks up some with the summer fuel. I don't drive my truck easy though and my tranny shift points are set so that I basically run at around 2k rpm all the time.
